An object of my invention is to provide a new, novel and improved tapfor a sealed container having a vent that is automatically opened andclosed as the tap is respectively opened and closed.

Another object of my invention is to provide upon a tap for a metalliccontainer means whereby the tap may be readily mounted in a wall of thecontainer at any desired point.

Figure 9 is a fragmentary view partially insection showing the manner ofmounting the tap upon a container having a conventional screw capclosure, and

Figure l0 shows an adaptation of tap to the neck of a bottle.

As illustrated in the accompanying drawing, the preferred form of myinvention comprises a to draw the bayonet I5 inwardly so into thecontainer and hold the abutting remaining portion of the threadedextension Il into close engagement with the-wall oi the container and,because of the disposition of the threads, insures a progressiveentrance of of the tap body into the wall of the container, as the tapbody is turned to move the bayonet in a circle. The end oi' the threadedextension I4, from which the bayonet I5 extends, is disposed at a rightangle to the axis of the bayonet and forms a shoulder I4' at each sideof the bayonet which will engage the wall of the container, when thebayonet has been projected therethrough, and hold' the bayonetperpendicular to the container wall and thus cause it to travel in acirclecorresponding to the curvature oi the bayonet. This type ofbayonet and threaded extension will cause the metal wall of thecontainer to be rolled back as a hole is out therein and provide metalupon which threads will be formed by the extension I4.

In the top of the valve body spout I3, there is a pose of permitting theentrance of air my improved the threadedA portion 35 sealed containerwhen the tap is applied as will hereinafter appear.
